Coolant leaking via Spring clip
 

Recently replaced my coolant reservoir and I notice that the coolant is leaking at the lower hose at the bottom of the tank via the spring clip.

Tried my best to squeeze that sucker on but it still leak when under pressure.

Has anyone every have that problem with coolant leaking from the spring clip?
Thinking of putting a high temp sealant until I can get the hose replaced. Ugh - now I have to drain again!!

Looking at REALOEM, I see the diagram for the hose but I don't see the part number. Anyone can direct me to the part number for this hose (see pic with red arrow)

There's a 0-ring inside these clip-on hoses that might need replacing. Easy fix but yeah, you'll have to drain it down again.

Really ? Never noticed one before on the hoses I have changed. Will have to check that.

Yep, it's the o-ring that actually seals the joint - the plastic is just to hold it all in place. ;)

Any chance they would sell these O ring at places like Autozone. What is the size? Not home yet to check the other hoses I have to confirm.

Very likely you can get one at Autozone etc. but I cannot help with the size, sorry. I cannot locate the diagram you show above on RealOEM anywhere so I cannot research it any further. It's a 2004 4.4i, right? N62 motor?

Your existing o-ring may be okay but have some foreign object (small piece of crap) caught in it. Cleaning it and lubing it with some coolant before assembly may help seal the joint. Clea down the mating tube face also.

Yup it's the N62. '04 4.4i

I looked at one of my old hose and it does have a ring wedged in there....never noticed.

Once I drain it i will use my pick tool to pull it out and take it to Autozone for a match.

Thanks for the feedback. Learned something new.

Next up...power steering return hose replacement.
